About this watch

First introduced as part of Rolex's mid-2000s expansion of the Lady-Datejust collection, the reference 178343 marked a pivotal moment when the manufacture refined proportions for smaller wrists while maintaining the sophisticated presence of precious metals and diamonds. This particular example showcases the reference's signature 24mm yellow gold case paired with a striking black concentric circle dial, featuring Arabic numerals that create bold contrast against the rich obsidian backdrop. The hypnotic concentric pattern draws the eye inward, while 24 diamonds set within the bezel catch and refract light with each subtle movement of the wrist.
